Resistance to triazoles has been reported on rare occasions, especially in immunocompromised patients.31 Non-albicans species are notorious for their resistance to azole agents. Fungal cultures are best to identify these species. Treatment with Nystatin has been well established.32 Boric acid, 600 mg in a gelatine capsule, used vaginally for 10 days, has also been shown to be highly effective in resistant cases.17 Recurrence is common if the full course of treatment is not completed and is also likely if there are predisposing factors

Diagnosis: The diagnosis is based on Amsel’s criteria.38 Three of the following four criteria are necessary to confirm the diagnosis of BV: 1. A raised vaginal pH >4.5 2.
